JPS6285543A - Originating control method for multiprocessor control exchange - Google Patents

Abstract

PURPOSE:To reduce the load of an interface processor and a basic module processor by completing all originating control processes independently and at an initial stage each process through an originator processor storing a terminal regardless of the position of a control originating processor. CONSTITUTION:If the congestion, etc. are detected with a basic module processor BM in an operation mode and the originating control is needed, the information on the necessity for control of all subscribers stored in an interface module processor IM is sent to this processor IM. The processor IM set this received information in an under-control display area and furthermore turns on the sound source of a control talkie device. In such a constitution, an off-hook state is informed to the processor BM in case an incoming bit is kept on or a control bit is kept off when the off-hook state of the IM is detected. Thus the BM carries out the normal processing. While the off-hook state of terminal is disused in case the incoming bit is kept off and the control bit is kept on respectively.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a system for restricting subscriber calls in an exchange controlled by a multiprocessor that employs a store-and-forward program system.

〔overview〕

In a call restriction method for a multiprocessor-controlled exchange, the interface module processor, which monitors and controls subscribers, and the basic module processor, which controls the exchange circuit, maintain incoming calls while discarding outgoing calls during a light chain. By executing call restriction in the processor based on a table rewritten by the basic module processor, it is possible to restrict information exchange between processors when calling is restricted.

[Conventional technology]

In a processing system such as a telephone exchange, processing congestion is constantly monitored, and if congestion is determined, calls that become a new processing factor are regulated. With this outgoing call regulation, each subscriber class can be freely selected to be subject to regulation.
If the restrictions are put into effect, calls made by the target subscribers will be connected to the control phone network.

On the other hand, all incoming calls and calls made by non-regulated subscribers are connected as usual.

FIG. 3 is a block configuration diagram showing the configuration of a multiprocessor regulated exchange. FIG. 4 shows the interface module processor (hereinafter referred to as 1M processor) in FIG.

) and a basic module processor (hereinafter referred to as 8M processor) are a flowchart illustrating processing related to call restriction.

Here, the 1M processor monitors the subscriber's off-footer and on-hook, and when this is detected, a notification to that effect is sent via the mask bus interface Wl (hereinafter referred to as the MIB device). Among these, during the outgoing call restriction processing at the time of off-footer, state management is not performed on the 1M processor, so it cannot be determined whether the call is off-hook for outgoing calls or off-hook for incoming calls. For this purpose, the off-hook signal from the 1M processor is unconditionally notified to the 8M processor. On the other hand, in the 8M processor, state management is performed for each terminal, and when an off-hook signal is received from the 1M processor, this state management table is referenced to identify outgoing calls and incoming call responses. Thereafter, it is determined whether the subscriber is under restriction, and if the subscriber is under restriction, it is subsequently determined whether the subscriber is subject to restriction. If it is determined that the restriction is to be implemented, the call will not be accepted and will be connected to the restriction talkie, and the process will be terminated.

[Problem that the invention seeks to solve]

As described above, in the conventional example, even after the restriction is activated due to congestion, outgoing calls are restricted, and the process of connecting the restricted talkie disappears after off-footer detection-communication-state determination is performed. Therefore, even though outgoing calls are restricted, each of the 1M processor, communication bus, and 8M processor requires processing.
The disadvantage is that the effectiveness of restrictions on outgoing communications is diminished.

The present invention eliminates the drawbacks that occur in the conventional outgoing call restriction applied to multiprocessor-controlled exchanges, and when the restriction is activated, the 1M processor independently terminates the restriction processing of the restricted subscriber in the process of subscriber off-hook monitoring processing. The purpose of this invention is to provide a method for regulating outgoing calls in a multiprocessor-controlled exchange.

[Means for solving problems]

The present invention includes a first step in which an interface module processor detects an on-hook state for each subscriber, and a second step in which a basic module processor determines whether this on-hook state is an on-hook state due to an incoming call or an on-hook state due to an outgoing call. , a third step of processing incoming calls and discarding outgoing calls; and a step of storing the determination result in the second step in the storage section of the interface module processor. , the interface module processor executes the third step based on the determination result stored in this step.

[Effect]

The basic module processor determines the light chain state, determines that the off-hook state is a call, and writes the results of this determination to the storage section of the interface module processor.

In the interface module processor, when an off-footer is detected, the call from the restriction-invoking subscriber is discarded based on the determination result stored in the storage unit.

On the other hand, when the caller is off-hook due to an incoming call, normal exchange processing is executed.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

FIG. 1 is a flowchart showing the process of calling restriction in the multiprocessor-controlled exchange shown in FIG. shows.

As shown in the figure, the 1M processor side has a table that can display restricted display bits and incoming call display bits for all subscribers, and each is normally set to an off state. Further, when a subscriber finishes a call or the like, a restricted talk trunk with the sound source turned off is connected to the subscriber as shown in FIG. When a subscriber receives an incoming call, the 8M processor sends an incoming call request to the corresponding subscriber to the 1M processor, and based on this, the 1M processor sets the subscriber correspondence bit in the incoming call display area to the ON state. It is set to the off state when the called party answers the incoming call or when the calling party abandons. In this way, when a light chain or the like is detected by the 8M processor during operation and it is determined that transmission regulation is required, information on whether or not all the aging public regulations required in the IM processor are stored is sent to the 1M processor.
In the M processor, this information is set in the restricted display area. Furthermore, the sound source of the restricted talkie device is turned on by the 8M processor. By taking the above steps, IM
If the incoming bit is on or the restriction focus is off when the processor off-hook is detected, an off-hook notification is sent to the 8M processor and normal processing is executed, and when the incoming bit is off and the restriction bit is on, this Terminal off-hook is discarded. This realizes outgoing call restriction processing.

In other words, in this embodiment, when outgoing call restriction is activated in a multiprocessor-controlled exchange, regardless of the location of the restriction-invoking optical processor, the originating processor accommodating the terminal independently performs all outgoing call restrictions at the initial stage of processing. can be completed, thereby reducing the load on the interface processor, master bus interface device, and basic module processor.

〔Effect of the invention〕

As explained above, in the present invention, processing related to call restriction when call restriction is activated in a multiprocessor-controlled exchange is performed independently by the end unaccommodated processor, so that the load on the entire system can be reduced. This has the effect of improving the quality of the system and making it more economical.
